Hi Brett, thanks, I think I've done the AAA krb auth right.

Ending up with this

Oct 17 15:54:52 sok5-f5 err websso.3[23639]: 014d0026:3: /Common/pptest2:Common:61e5157b: Could not find SSO username, check SSO credential mapping agent setting
Oct 17 15:54:52 sok5-f5 debug websso.3[23639]: 014d0041:7: /Common/pptest2:Common:61e5157b: Could not find SSO domain, using default realm defined for Kerberos SSO object
Oct 17 15:54:52 sok5-f5 err websso.3[23639]: 014d0043:3: /Common/pptest2:Common:61e5157b: SSO username is empty - SSO is disabled

I can see the authenticated session. Variable session.logon.last.username by AAA is something like this user@KRB-REALM.ORG. Is the right thought that this should be mapped to be used by SSO (backend krb delegation) to defined variables (session.sso.token.last.username and session.ad.last.actualdomain in this scenario) by SSO credentail mapping? Can you advise me me how to achieve this?
